Question

Solve these pair of linear equation by elimination x+y=14 and x-y=4

Answer 1

Answer:

let's take x+y=14 as eq 1

and x-y=4 as eq 2

so now add eq's 1 +2

it gives 2x=20so x=10

hope this helps you

Step-by-step explanation:

Answer 2

Step-by-step explanation:

x + y = 10..........1

x - y = 4............2 add 1 and 2

-------------

2x+0= 14

therefore x = 14/2 => 7

7 + y = 10 [ putting the value of x in equation 1 ]

=> y =10 - 7 => 3

x = 7 and y = 3
